Leading from the lower portion of radiator 16 to the chamber Within housing 12 above plate 16 is a tubular con nection 31 and connected thereto is a Valve housing 32 in which is formed a valve seat 33. Adapted to rest on this seat is a valve 3 the same being carried by a stem 3 which projects through the top of housing 32 and carried by the upper end of said stem is a soft metal disk or plate 36 which performs the functions of an armature.

interposed between valve 34 and the top of the housing 32 is a relatively light compression mally hold valve 34: upon seat 33, thereby cutting off the flow of water of condensation from the radiator body to the electrically heated steam generator.

Arranged on a suitable support above the valve housin 32 is an electro-magnet 38, the core of: w ich is disposed directly above the disk 36. Leading from a suitable source of electrical energy to one of the b1nd1ng posts 2% is a conductor 39 and leading from the other binding post to one of the terminals of the heating coil is a conductor a). Leading from the other terminal of the heat ing coil to the source of electrical energy 15 a conductor 41. Leading from conductor 40 to one end of the coil of is a conductor 42, and leading from the opposite end of said coil to conductor 41 is a conductor 43.

Water of condensation from the body of the radiator 10 enters the chamber within housing 12 above the plate 16 and said Water flows through the grooves 18 and 1S), and after passing through apertures'20. drops onto the inclined portions 22 of the spreader plates 21. This water flows downwardly over said plates in relatively thin iihns and finally drops onto plate 13. This plate is heated to a relatively high degree by the coil or coils 15, the latter being supplied with current through conductor 11, and as a re suit, the water is very rapidly converted into steam and the latter passes upwardly and is conveyed through pipe 17 to radiator 10.

Necessarily, the pressure in the chamber above plate 16 is the same as in the chamber between said plate and plate 13 and when a predetermined degree of pressure prevails, piston 26 is forced upward against the resistance oilered by spring 30 with the result that plate 29 leaves contact members 24,

thereby opening the circuit in which the lid till

heating coil is located and which circuit in-- cludes conductors 39, t0 and 41. Simul .taneous.with this opening of the main circuit, the flow magnet 38 will be cut ed with the result that spring 37 will act to position valve 34: upon its seat 33, consequently cutting 0d the flow of water of condensation from the radiator aa 10 to the steam generator. This condition spring 37 which tends to nor-- the electrically heated steam elcctro-magnet 38 of current through electro ac/cam will prevail until the temperature of the radiator lowers sufficiently to reduce the pressure within the steam generator, whereupon spring 30 will. act to move piston 26 downward, and consequently moving plate. 29 into contact with members 24, thereby closing the circuit to the heating coil 13. Simultaneous with this closing of the main circuit,,electro-magnet 38 will be energized, with the result that disk 36, stem 35 and valve 34 will be elevated, thereby permitting the water of condensation to again flow from radiator to the steam generator. Thus the action of the steam generator is automatically controlled by the pressure within said generator." One end of the radiator is provided with a. normally closed inlet opening or filling spout as shown in Fig. 1.

In Fig. 5 I have shown a modified form of generator this construction including a housing 45 provided in its lower portion with a plate 46 below which is arranged the heating coil 47. Arranged in the upper portion of the housing is a plate 48 from which depends a series of open-ended tubes $9, the latter passing through conical apertures 50 in a plate 51, the latter being located a short distance below plate dVhere this construction is provided, water enters the chamber between plates 48 and 51. and passing through the apertures 50 travels downward over the surface of the tubes 49 and drops therefrom onto plate at; and as the Water is converted into steam, the latter passes upward through pipes 49 and passes from the housing 45 to the radiator.

Radiators of my improved construction can be usedhvherever a suitable electric current is available and for household use the steam generator can be directly connected to the radiator, thereby enabling the latter to be readily moved from one oint to another and positioned wherever esired.

The automatic control of the heating coil enables the radiator to be economically used, for by such control a sufficient degree of heat is obtained with a minimum consumption of electric current.

It will be readily understood that minor 115 changes in the size, form and construction of the various parts of my improved radiator may be made and substituted for those herein shown and described; Without departing from the spirit of my invention, the 120 scope of which is set forth in the appended claims.
